I really liked this! I think combining all the mechanics into one action (one versatile verb, if you will :^)) made it very interesting. I agree with the other commenters that the controls could be a bit frustrating, but it is a gamejam game so I understand. I think if the recharge time was faster it would feel a little less frustrating -- it definitely felt at times like I knew exactly what I needed to do but I was being limited by having to wait for my air to recharge. An alternative fix could maybe be to allow you to burp with not-full air with a smaller boost?
Regardless, I really like this game and it was very satisfying when I finally beat it :)
